Influence of     2 1 ,   , l  on q  The values of temperature difference     1 2 t t t    (Fig. 1) and heat fluxes     1 2 q q q    (Fig. 2) for different parameters influential on coefficient of contact thermal conductivity h (hardness  , purity l  , conductivity     2 1 ,   , pressure P ) are obtained. Conclusions. After analysis of the numerical results, we can obtain following conclusions: 1) coefficient of thermal conductivity grows with growth of corresponding thermal conductivity of contact bodies and pressure in the contact area, and
